Description

technical field [0001] The invention relates to a frequency resource allocation and use technology of wireless communication technology, in particular to a networking system and an allocation method for adaptive allocation of discrete spectrum on the power consumption side. Background technique [0002] According to the former State Radio Regulatory Commission's "Notice on Printing and Distributing Frequency Band Planning for Civilian Ultrashort Wave Telemetry, Remote Control, and Data Transmission Services" (Guowuguan [1991] No. 5), in the 223.025-235.000MHz frequency band, with 25kHz as a frequency point width, divide There are 15 pairs of duplex frequency points and 10 simplex frequency points, a total of 40 frequency points and frequency resources of 1MHz bandwidth, which are used for the load monitoring system of the power system in terms of energy supply. [0003] The 40 frequency resources are discretely distributed, and they were mainly used by 230 digital radio stat...

Problems solved by technology

[0003] The 40 frequency resources are discretely distributed, and they were mainly used by 230 digital radio stations earlier. The frequency points pre-configured during station installation are used between the master station and the slave station for point-to-point communication; the frequency points of the slave stations are networked within a certain area When planning, according to the principle of non-overlapping interference, the distribution is staggered. Once the pre-planning of frequency resource allocation is completed and relevant configurations have been made in advance in the digital transmission station, the station will always use this pre-configured frequency during operation. Point resource, the frequency point resource allocated to each radio station, is fixed and unique, that is, only a single fixed frequency point of 25kHz narrowband communication can be realized

Although this rate value can meet the communication needs of the collection terminal with a small amount of single-point data on the power consumption side, point-to-point and polling data transmission is somewhat insufficient when a large number of data collection terminals are concurrently transmitted.

In addition, the working frequency of the digital radio station is pre-configured during installation, and cannot be adjusted automatically after being put into use. Data transmission will be seriously affected when sudden strong interference occurs, and the accurate and reliable transmission of power user business data on the power consumption side cannot be guaranteed.

[0005] The 230MHz frequency band is the golden frequency band for data transmission. The single-frequency 25kHz narrowband transmission mode of the data transmission station has a low spectrum utilization rate, which does not conform to the trend of the growing wireless communication technology in terms of spectrum efficiency.
